My invention relates to valves and in a valve whichwill etfecta positivemetering crating liquid level indicating gauges'and It is will act as a seal between a "liquid-column a'ndan air column orbetween two different liquid columns, thus permittingthe use of a liquid column instead ofair for the operation of hydrostatic gauges or otherlike de-.

vices.

with various types of gauges'in which-it panel It is my object to provide a valve which furnishes ashut-ofi' when the pressure applied to it-has moved the -metering element its prescribed length, or travel, and will also shut off in the reverse direction when presa vacuum takesplace or air from the indicating gauge;

My present application is confined to the valve filed to cover the combination of this valve produces new and novel results. Referring to the drawings: Figure l is'a perspective of a strip chassis with the dash board and one side frame member broken away showing the typical installation of the valve which is the subject matter of the present application, in connection with various types of gauges;

Figure 2 is a view of the dash board Figure 3 is a section through the valve;

Figure 4 is a section through a modified form of valve.

Referring to the drawings in detail, 1 is a dash board of an automobile onwhich is; mounted a panel plate 2 having gauge indicating-devices for indicating the quantity of gas in the tank 4 through the opening'3, the oil level at 5, the. oil pump operation at 6, the water height at 7 and the temperature at 8, while the condition of the electrical system is'indicated by a meter 9. i

. The water height is indicated by a hydro-' gauge generally designated 10, in-the which is located one of the valves now static line of in question, marked 11. v The iii pump indicating line 12 has a. sue:

particular to valves adaptablefforuse in 'connecstionwith gauges on automotive equipment. It is theobjectof my invention to, provide;

' thevalve consists of alo predetermined\moves passageway..15 therein, which; I ment ofan air or liquid column used in 0p myobject to. providea valve Which threads; of the,

wer tubular member 1 4, hav1ng, a terminates at 16. .;,.Around this openinglbis a resilient washer 17 carried in a cup 18 of the bottom 19 01? the chamber 2O. This bottom has an angular portion 2- internally threaded at 22 for receiving the external 7 side walls 23 of the chamber. These side {walls are carriedon a :headf24,

which is provided with a'nflinteriorltubular portion 25. ".Around th l mouth this tubul i ortion 2 5 is ,a second; resilient washeri26. 4 '7 u a Willb noted that} f Within the tubular member 25 is fitted so that it can movefre'ely but closely adjacent theretoa tubular member 27 which is mount ed upon a valve member 28 consisting of a flat bottom portion 29 and a dome portion. This valve member is adaptedto move upwardly where it will seal the movement of liquid or gases completely when it is in its uppermost position, and will move downwardly and effect the same result in its lowermost position.

Turning to F igureet, it will be observed thatFigure 4 is provided with a tubularv14E having a'passageway l5 ter-f' in a flared opening or valve seat 30 in which fits a needle valve member31 I when it is in its lowermost positioni The tubular member 14 terminates in a cup'32 onwhich isthreadedan inverted cup 33. Between the cups are mounted packing or washing members 34 carrying between them a diaphragm 35 of rubber, leatheryorthe like, or metal, if desired. In the center of this diaphragm is carried the needle valve 31 which'is threaded on a valve stem .36 which is sufficiently restricted in diameter to pass freely within thetubular portion 37 in the passageway 38. A washer 26 is provided around the lower lar portion or opening 38.

It is apparent that when this diaphragm is in its uppermost position, the upper tubu-f l ar member will be sealed and when it is in-its lowermost position, the tubular portion 33 will be sealed.

corresponding movement of the moving parts. A sliding engagement between the tubular member and one of the passageways is of such a character and of such close fit that a substantial seal is effected i or practically all liquids utilized in so that the contents of one passageway will be prevented from entering the other passageway and mixing with the contents thereof. p t

In the form shown in Figure 3, it is obvious that there can be a slight passage of but in Figure 4, there will be no passage of such materials.

Itwill be understood that I desire to comprehend within my invention such modifications as may be necessary varying conditions and uses. 7

Ha'x' ing thus fully described my invention,

what I claim as new and desire to secure by Letters-Patent, is a 1. In avalve, a two-part valve chamber, eachzp'ar'tof said chamber having a pasa valve member adapted to alternately seal said passageways and means for guiding said valve member in its movement the contents of one passageway to adapt it to from one position to the other, means consisting of a tubular member fitting closely within one of said passageways, the close fit of said tubular member being such as to practically seal one passageway from the other, preventing the entrance 0 into the other passageway.

2. In a valve, a two-part valve chamber, each part of said chamber having a passageway, a valve member adapted to alternately seal said passageways and means for guiding said valve member in its movement fromone position to the other, said guiding means consisting of a tubular member fitting closely within one ofsaid passageways, the joint between the tubular member and one of the passageways being so arranged a to practically seal the connection between the passageways, mouth of the passageways for cooperating in the sealing of such passageways when the valve member is in suitable position.
